Definitions

the invention relates to an electric motor drive, in particular for a Pump for an electro-hydraulic vehicle steering device, with a motor mount, which has a cylindrical pin, and with a drive windings having stator, which of the cylindrical pin of the Motor bracket is penetrated and held by this.
electro-hydraulic vehicle steering devices are usually used electric motor driven pumps, these drives for a short-term operation are designed at full load.
Well-known motors for electro-hydraulic Steering devices generate disturbing noises in full load operation, which is essentially due to high-frequency fluctuations in the drive can be attributed to occurring torque.
Electric motors known electromotive drives or pumps have a stator and a rotor realized as external rotor, which is the stator cup-shaped includes.
the stator sits on a cylindrical pin, which is made by an engine mount is formed and from which it is penetrated.
This cylindrical pin is often formed as a hollow cylindrical bearing shaft.
Lagerschaft serves to accommodate and rotatable mounting of a drive shaft of the electromotive drive.
the drive shaft is in turn connected to the rotor in appropriately connected.
the drive is usually for protection purposes
Enclosed drive housing which is connected to the motor bracket.
the gap Between the inner wall of the stator and the outer wall of the bearing shaft a gap is provided, the gap preferably at least partially with filled with a viscous medium.
the introduction becomes more flexible Elements such as O-rings are proposed in the gap. That way, one becomes achieved reduced coupling of stator and bearing, through which no significant Torque transmission is possible, which, however, favorable to the Noise emissions of the drive.
the filling of the gap means between the inner wall of the stator and the outer wall of the bearing shaft with a viscous medium or attaching additional flexible vibration-damping elements for bridging the gap increased Production costs and thus increased costs in the production.
the invention is therefore based on the object, an electromotive Drive, in particular for a pump for an electro-hydraulic vehicle steering device, in which an improved suppression of the known drives occurring during operation noise by simple constructive measures is guaranteed.
the stator is in addition by the tolerance ring against movement in axial Direction secured along the cylindrical pin of the motor mount.
the Use of an axial splint or a spiral tension pin is according to the invention not necessary, which also eliminates the need to appropriate Provide grooves on stator and motor bracket. Likewise, no additional Retaining element needed for axial securing of the stator. Elaborate constructive Measures are not required. Thus, the inventive electromotive drive overall in a simplified manner and therefore also produce more cheaply.
FIG. 1 shows an electromotive drive in an embodiment of the invention Invention with a motor mount 1, which has a cylindrical pin second and a stator 3 mounted on the cylindrical pin 2 cylindrical pin 2 of the motor mount 1 is a hollow cylindrical bearing shaft. 5 designed for rotatable mounting of a drive shaft of the drive.
a the Stator 3 cup-shaped comprehensive rotor is not shown in the figure.
the rotor is designed as an external rotor and is within the housing 1 by means of a fixed rotatably mounted in the bearing shaft 5 connected to it drive shaft. The entire arrangement is of a likewise not shown in the figure Enclosure enclosed.
the sleeve-shaped formed tolerance ring 4 a wave-shaped course along the circumference its inner wall. He is on the front of the assembly of the stator 3 Motor holder 1 inserted into the stator 3 and fixes this in a press fit after mounting on the cylindrical pin 2.
the waves along the Inner wall of the tolerance ring 4 are based on the outer wall of the cylindrical pin 2 in the axial recess 6 from.
a material for the tolerance ring 4 is for example carbon steel or stainless Spring steel use.
the sleeve-shaped formed tolerance ring 4 a wave-shaped course along the circumference its outer wall, as shown in Figure 3. Also in this way is at the assembly achieved a press fit between the stator 3 and motor mount 1.
the Shafts along the outer wall of the tolerance ring 4 are based on the Inner wall of the stator 3 from.
Use of a tolerance ring for torque transmission between stator 3 and motor bracket 1 results in a concentric bearing of the stator. 3 with respect to the cylindrical pin 2 of the engine mount 1 in any operating condition of the drive and over a wide temperature range of about -40 ° C up to + 120 ° C.
Disturbing noise-producing vibrations of the system Stator / motor mount are essential by this concentric storage reduced.
